Take-up device for the take-up of insulating fluid and housing having the take-up device

Abstract

A take-up device for the taking-up of insulating fluid from a tank of a transformer or a reactance coil. The take-up device has a compensator, which is configured as a hollow body with a variable compensator volume, and is connectable to a tank opening of the tank, such that insulating fluid can flow through the tank opening between the interior of the tank and the compensator volume.

1 . A take-up device for taking-up insulating fluid from a tank of a transformer or a reactance coil, the take-up device comprising:
 a compensator configured as a hollow body with a variable compensator volume, and is connectable to a tank opening of the tank, such that the insulating fluid can flow through the tank opening between an interior of the tank and the variable compensator volume.   
     
     
         2 . The take-up device according to  claim 1 , further comprising a retention and release device which prevents an increase in the variable compensator volume, provided that an internal pressure in said compensator does not exceed a threshold pressure value, and which permits an increase in the variable compensator volume, if the internal pressure in said compensator exceeds the threshold pressure value. 
     
     
         3 . The take-up device according to  claim 1 , further comprising a displacement container which can be disposed in an interior of said compensator and hermetically sealed in relation to said compensator, or is connectable to the tank opening in place of said compensator, such that the insulating fluid can flow through the tank opening between the interior of the tank and an interior of said displacement container. 
     
     
         4 . The take-up device according to  claim 3 , wherein said displacement container is configured as an expansion tank for a take-up of the insulating fluid from the interior of the tank through the tank opening. 
     
     
         5 . The take-up device according to  claim 4 ,
 further comprising a gas container with a variable gas container volume disposed in said displacement container; and   wherein said displacement container has a closeable gas opening which communicates with the variable gas container volume such that, when said closesable gas opening is open, gas can flow between said variable gas container volume and the tank environment, if said displacement container is connected to the tank opening.   
     
     
         6 . The take-up device according to  claim 5 , wherein said gas container is configured as a rubber bag. 
     
     
         7 . The take-up device according to  claim 3 , wherein said displacement container is provided with a Buchholz relay connection for a Buchholz relay. 
     
     
         8 . The take-up device according to  claim 3 , wherein said displacement container is configured as a cup-type hollow body. 
     
     
         9 . The take-up device according to  claim 3 , wherein said displacement container is manufactured from a metallic material. 
     
     
         10 . The take-up device according to  claim 3 , wherein said displacement container has a displacement container flange which is configured for a removable attachment of said displacement container to the tank, optionally closing the tank opening, or to said compensator, optionally closing a compensator opening. 
     
     
         11 . The take-up device according to  claim 10 , wherein said compensator has a first compensator flange, to which said displacement container flange is removably attached to close said compensator opening. 
     
     
         12 . The take-up device according to  claim 11 , wherein said compensator is provided with a second compensator flange configured for a removable attachment of said compensator to the tank, thus closing the tank opening of the tank. 
     
     
         13 . The take-up device according to  claim 1 , wherein said compensator has a bellows for configuring the variable compensator volume. 
     
     
         14 . The take-up device according to  claim 13 , wherein said compensator is one of at least two compensators, which differ from each other in respect of a hardness grade of said bellows. 
     
     
         15 . A housing of a transformer or a reactance coil, the housing comprising:
 a tank with a tank opening formed therein; and   a take-up device for taking-up insulating fluid from said tank, said take-up device containing a compensator configured as a hollow body with a variable compensator volume, and is connected to said tank opening of said tank, such that the insulating fluid can flow through said tank opening between an interior of said tank and the variable compensator volume.
